You need to watch the prices very carefully. At times the DDR platform is more expensive than the RDRAM platform (I'm talking about the Dell Dimension computers). But most of the time (including today) the DDR at Dell is much cheaper. I need to help my school purchase about 50 computers and Dell is selling the DDR Dimension about $100 less than the RDRAM dimension. That is great, except I need the Optiplex and there isn't a DDR Optiplex. I'm so worried that they will be getting SDRAM to save that money. 🙁
Dell should have a DDR Optiplex.
However I disagree with this statement: "DDR and DDR II are going to be around longer than Rambus and the prices will flip again as Rambus systems age and DDR becomes the norm." There has been no evidence to support that at all. Rambus has been gaining market share of new computers, Rambus is set to have the fastest memory in May (lowest latency and greatest bandwidth). Rambus prices have consistantly and slowly fallen since the beginning of RDRAM. DDR prices have been going the other way for 6 months. Although DDR is gaining market share, it is at the expense of SDRAM and not at the expense of RDRAM. Who knows about the future, but for now, there is no sign of RDRAM leaving. Talk to me in 2 years and then I may very well agree with you (or you might be eating your words).
